ftp_nlist
Directly from bsd FTP manual pages:
The PASV command requests that the remote server open a port for the data connection and return the address of that port. The remote server listens on that port and the client connects to it.
When using the more traditional PORT command, the client listens on a port and sends that address to the remote server, who connects back to it. Passive mode is useful when using ftp through a gateway router or host that controls the directionality of traffic. (Note that though ftp servers are required to support the PASV command by RFC 1123, some do not.)
ftp_pasv
(PHP 4, PHP 5)
ftp_pasv — Turns passive mode on or off

( resource $ftp_stream
, bool $pasv

Please note that ftp_pasv() can only be called after a successfull login or otherwise it will fail.
Parameters
- ftp_stream
-
The link identifier of the FTP connection.
- pasv
-
If TRUE, the passive mode is turned on, else it's turned off.
Return Values

Examples
Example #1 ftp_pasv() example
<?php
$file = 'somefile.txt';
$remote_file = 'readme.txt';
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// turn passive mode on
ftp_pasv($conn_id, true);
// upload a file
if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
echo "successfully uploaded $file\n";
} else {
echo "There was a problem while uploading $file\n";
}
// close the connection
ftp_close($conn_id);
?>

PASV: For ftp users behind firewall, the server LISTEN for a connection.
Non-PASV: The client LISTEN for a connection from server.
